information is mostly useful to programmers who are working on the

program to compile and work.

+Where long and short forms of an option are shown together, they are

+.TP
+.B \-\-archive\-headers
If any files from \c

header information (in a format similar to `\|\c

the object file format of each archive member.

-You can specify a particular object-code format for your object files as
+.BI "\-b " "bfdname"\c

+.TP
+.B \-\-debugging
+Display debugging information. This attempts to parse debugging
+information stored in the file and print it out using a C like syntax.
+Only certain types of debugging information have been implemented.
+
.TP
.B \-d
-Disassemble. Display the assembler mnemonics for the machine

+.B \-\-disassemble
+Display the assembler mnemonics for the machine
instructions from \c

\&.
+This option only disassembles those sections which are
+expected to contain instructions.
+
+.TP
+.B \-D
+.TP
+.B \-\-disassemble-all
+Like \fB\-d\fP, but disassemble the contents of all sections, not just
+those expected to contain instructions.
+
+.TP
+.B \-\-prefix\-addresses
+When disassembling, print the complete address on each line. This is
+the older disassembly format.
+
+.TP
+.B \-\-disassemble\-zeroes
+Normally the disassembly output will skip blocks of zeroes. This
+option directs the disassembler to disassemble those blocks, just like
+any other data.
+
+.TP
+.B \-EB
+.TP
+.B \-EL
+.TP
+.BI "\-\-endian=" "{big|little}"
+Specify the endianness of the object files. This only affects
+disassembly. This can be useful when disassembling a file format which
+does not describe endianness information, such as S-records.
.TP
.B \-f
-File header. Display summary information from the overall header of
+.TP
+.B \-\-file\-headers
+Display summary information from the overall header of
each file in \c
-.I objfiles\c
+.I objfile\c

-.B --header
-Header. Display summary information from the section headers of the

+.B \-\-headers
+Display summary information from the section headers of the
object file.
+.TP
+.B \-\-help
+Print a summary of the options to

.TP
.B \-i
+.TP
+.B \-\-info
Display a list showing all architectures and object formats available
for specification with \c

\&.
.TP
-.BI "-j " "name"\c
-\&
+.BI "\-j " "name"\c
+.TP
+.BI "\-\-section=" "name"
Display information only for section \c

+\&.
.TP
.B \-l
-Label the display (using debugging information) with the source filename
-and line numbers corresponding to the object code shown.
+.TP
+.B \-\-line\-numbers
+Label the display (using debugging information) with the filename
+and source line numbers corresponding to the object code shown.
+Only useful with \fB\-d\fP, \fB\-D\fP, or \fB\-r\fP.
.TP
-.BI "-m " "machine"\c
-\&
-Specify the object files \c
-.I objfiles\c
-\& are for architecture
-\c
-.I machine\c
-\&. You can list available architectures using the `\|\c
-.B \-i\c
-\|'
-option.
+.BI "\-m " "machine"\c
+.TP
+.BI "\-\-architecture=" "machine"
+Specify the architecture to use when disassembling object files. This
+can be useful when disasembling object files which do not describe
+architecture information, such as S-records. You can list the available
+architectures with the \fB\-i\fP option.
.TP
.B \-r
.TP
-.B --reloc
-Relocation. Print the relocation entries of the file.
+.B \-\-reloc
+Print the relocation entries of the file. If used with \fB\-d\fP or
+\fB\-d\fP, the relocations are printed interspersed with the
+disassembly.
+
+.TP
+.B \-R
+.TP
+.B \-\-dynamic\-reloc
+Print the dynamic relocation entries of the file. This is only
+meaningful for dynamic objects, such as certain types of shared
+libraries.
.TP
.B \-s
+.TP
+.B \-\-full\-contents
Display the full contents of any sections requested.
.TP
-.B \--stabs
+.B \-S
+.TP
+.B \-\-source
+Display source code intermixed with disassembly, if possible. Implies
+\fB-d\fP.
+
+.TP
+.B \-\-show\-raw\-insn
+When disassembling instructions, print the instruction in hex as well as
+in symbolic form. This is the default except when
+.B \-\-prefix\-addresses
+is used.
+
+.TP
+.B \-\-stabs
Display the contents of the .stab, .stab.index, and .stab.excl
sections from an ELF file. This is only useful on systems (such as
Solaris 2.0) in which .stab debugging symbol-table entries are carried
in an ELF section. In most other file formats, debugging symbol-table
entries are interleaved with linkage symbols, and are visible in the
---syms output.

+.TP
+.BI "\-\-start\-address=" "address"
+Start displaying data at the specified address. This affects the output
+of the
+.B \-d\c
+,
+.B \-r
+and
+.B \-s
+options.
+
+.TP
+.BI "\-\-stop\-address=" "address"
+Stop displaying data at the specified address. This affects the output

.TP
.B \-t
.TP
-.B --syms
+.B \-\-syms
Symbol Table. Print the symbol table entries of the file.
This is similar to the information provided by the `\|\c
.B nm\c
\|' program.
+.TP
+.B \-T
+.TP
+.B \-\-dynamic\-syms
+Dynamic Symbol Table. Print the dynamic symbol table entries of the
+file. This is only meaningful for dynamic objects, such as certain
+types of shared libraries. This is similar to the information
+provided by the `\|\c
+.B nm\c
+\|' program when given the
+.B \-D (\-\-dynamic)
+option.
